Details: WHAT MAKES WL CALF STRETCHER SPECIAL  Instead of wood or plastic like other boards on the market, WL calf stretcher is made of steel so that it can handle your bodyweight without risk of getting broken or bent. The 16”x14” wide non-slip surface on top will provide enough space to put both of your feet on the board. This helps you realize if there’s a tighter leg than the other, which can be a potential imbalance and injury risk.  IDEAL FOR ALL AGES AND FITNESS LEVELS  Whether you are a beginner or an advance user, you’ll be able to use our angle-adjustable slant board without pain and difficulty. With 4 angles to use – 15, 25, 30 and 35 degrees, start with the lowest angle to prevent injury and then increase the slope gradually for deeper stretches.  A MUST-HAVE PHYSICAL THERAPY EQUIPMENT  Calf stretcher is usually used in the rehabilitation of Achilles tendon, patellar tendonitis, shin splints and other lower leg injuries. Or you can use the board as an ergonomic foot rest under your office desk to release ankle, heel, calf, thigh tensions and reduce back pain. For other fitness enthusiasts, standing on a slant board is a great way to make common exercises more challenging as well as improve their balance and flexibility.  EASY STORAGE AND TRANSPORT  With the compact and foldable design, you will be able to fold the calf stretcher down instantly and put them in any corner of your room.  FEATURES  Material: Steel Dimensions: 16”x14”x1.5” (L x W x H)  Color: Black Weight: 7.5 lbs  Four different angles: 15, 25, 30 and 35 degrees  WARRANTY This calf stretcher comes with a 30 days money back and 1 year replacement.
